[4.9.18] - 2020-04-28

Heatmaps can now be logarithmic (set logarithmic = true in the heat rule config).

Preloader label was misaligned when RTL was enabled.
Double "hit" event invocation on MapPolygon fixed.
Regression plugin: "processed" event was triggered twice on initial chart load.
SliceGrouper plugin: if slice templats had any "hit" events set, clickBehavior = "break" was not working.
IE was not displaying series in XYChartScrollbar. On IE now gray fill/stroke is used instead of desaturate filter.
IE was not displaying series with filters. Remnoved filters if IE.
Fixed issue with zero-value nodes drill-down SankeyDiagram.
When animations were disabled through options, showing XYSeries and FunnelSeries after it was hidden was not working.
It was not possible to add MapImages to MapImageSeries directly from the GeoJSON geodata.
maxWidth set on Legend's label was being ignored.
Layout was not being redrawn when minGridDistance was set after chart initialization.
If sprite.showTooltipOn = "hit" and no animated theme was used, tooltip used to flicker at old position before shown in the correct one.
EDGE was not showing ColumnSeries gradients if gradient was set on series, not on directly on column template.
